Rodolfo Alonso Hernandez 84b3ae3ae9 Linux Bridge: driver support for QoS egress minimum bandwidth
This patch provides the Linux Bridge agent driver the ability to control
Linux Traffic Control (TC) to set the minimum required transmission rate
for an interface.

The TC library is refactored to use HTB qdiscs. This allows TC to
define, for several flows in the same interface, the maximum and the
minimum network bandwidth and the burst size.

To be able to do traffic shaping (instead of policing) for ingress
traffic, a new element, the Intermediate Functional Block device (IFB)
is introduced.
